Question
$z$ is multiplied by $-3$ and the result is subtracted from $13.$
✓
Answer
According to the question, $z$ is multiplied by $-3 = (-3) \times z$
Now, result is subtracted from $13 = 13 - (-3)$
$z = 13 + 3z $
Hence, the required expression is $13 + 3z.$
Now, result is subtracted from $13 = 13 - (-3)$
$z = 13 + 3z $
Hence, the required expression is $13 + 3z.$
